A single I3S data set, referred to as a Scene Layer, is a container for arbitrarily large amounts of heterogeneously distributed 3D geographic data. Scene Layers are designed to be used in mobile, desktop, and server-based workflows and can be accessed over the web or as local files.
These release notes describe in detail the changes and enhancements to the original OGC I3S Community Standard. These release notes describe the changes that comprise the 1.1 revision. This I3S revision, including all the changes and enhancements, is backwards compatible with version 1.0 (17-14r5) of the I3S Community Standard.
